5.4 x 4.4 x 3.6 cm. A beautiful combo specimen of gemmy quartz crystals, a couple of them doubly-terminated, with a round cluster of translucent prehnite of a gorgeous light mint green. The two minerals complement one another beautifully on this specimen! Good prehnites are common now from Mali and to some extent from New Jersey, but NOT from China!
